Springs, Colo. during a Vigilant Guard exercise, July 22, 2013. The Vigilant Guard exercise is a weeklong exercise full of scenarios based on wildfires, tornadoes, air craft accidents, hazmat response, search and rescue, triage, medevac and other emergency-response measures. The training and experience gained from this exercise will provide the Colorado National Guard and supporting military units an opportunity to improve cooperation and operational relationships with their local, state, private sector, non-governmental organizations and federal partners.
